What movie is the most historically accurate

No single film is universally the "most" historically accurate because accuracy depends on the event, the filmmakers’ goals, and which kinds of accuracy you value (events, timeline, character, material culture, or motives). However, historians often praise these films for high levels of accuracy in various respects: - Spartacus (1960) — praised for realistic depiction of slavery and Roman material culture, though characters and politics are dramatized. (Peter Green, The Roman World) - Zulu (1964) — accurate in battle tactics, uniforms, and terrain for the 1879 Battle of Rorke’s Drift, though some individual actions are fictionalized. (Ian Knight, Zulu Rising) - Das Boot (1981) — lauded for authentic submarine life, procedures, and atmosphere. (Film based on Lothar-Günther Buchheim’s novel) - Downfall (2004) — closely follows documented final days in Hitler’s bunker using primary sources and memoirs. (Joachim Fest, Traudl Junge) - Schindler’s List (1993) — widely regarded as faithful to the Holocaust’s essential facts and many documented events, though some composites and dramatizations occur. (Thomas Keneally, Schindler’s Ark) - The Right Stuff (1983) — respected for accurate portrayal of early U.S. astronaut culture and flight testing, with some compressed timelines. (Tom Wolfe, The Right Stuff) - 12 Years a Slave (2013) — based on Solomon Northup’s memoir; noted for faithful representation of slavery’s brutality and many documented episodes. If you name a specific historical event or figure, I can recommend the most accurate films for that topic and note their main distortions.
